There’s nothing wrong at all with your multicast function, you just need to replicate the shield variable.

UPROPERTY(EditDefaultsOnly, replicated, Category = "MyVars")
	AActorShield* shield;

void AMyProjectCharacter::GetLifetimeReplicatedProps(TArray< FLifetimeProperty > & OutLifetimeProps) const
{
	Super::GetLifetimeReplicatedProps(OutLifetimeProps);
	DOREPLIFETIME(AMyProjectCharacter, shield);
}
